Arterial occlusive disease peripheral chronic I73.9

Generic term for a chronic vascular disease with an intermittent or uniformly progressive course that can lead to organic stenosis or obliteration of the aorta and the arteries supplying the extremities. The diagnosis of a chronic arterial occlusive disease requires information on its localization and severity.

Chronic peripheral arterial occlusive disease is accompanied by thickening, hardening and narrowing of the vessel wall due to the accumulation of lipids, proteins and calcium. Secondary ulceration of atheromatous plaques, subintimal bleeding and localized thrombosis. Occurrence of clinical symptoms with at least 50% narrowing of the vascular lumen. Dermatologically relevant is especially the chronic arterial occlusive disease of the legs.

With a share of >50%, cerebral (14.3%), peripheral (17.9%) and cardiac (18.1%) vascular processes are the most common diseases in industrialized countries. Compared to patients without PAD, patients with PAD have a 3-5 times higher cardiovascular mortality. The risk of apoplexy is 2 times higher.

Chronic peripheral arterial occlusive disease is of arteriosclerotic origin in > 90% of cases.
